I had a great stay at Phil's place. The room was very clean, has a huge double bed with a view over a market and canal over the road outside and has good air-con and WIFI. It's situated in a quiet road a 20 minute walk north of the Kao San, and 5 minutes from a main road for catching taxis and picking up some great street food.
Communication with Phil prior to arrival was really good! He responds promptly and gave me all the information I needed re. getting there from the airport, self check-in and info' about the room.
I would definitely stay at Phil's place again and can recommend it.
